AVoltage, path, duration and frequency
BCurrent, power, duration and polarity
CVoltage, power, resistance and polarity
DCurrent, path, duration and frequency
Answer & Solution
Correct answer: D. Current, path, duration and frequency
1. The four factors are the amount of current, the path it takes, how long it lasts and its frequency.
2. Direct current counts as the special case of zero frequency.
3. Voltage matters only through I = V / R, so it is the current that appears in the list rather than the voltage.
4. That is why no voltage can be called hazardous without also knowing the resistance in the path.
5. Options naming voltage directly confuse the cause with the quantity that actually does the damage.
